- I modified a ][+ recently to give it lower case so this is fairly fresh in
- my mind. I used the blanket approach too. I did both the "shift-key mod"
- that involves running a wire from one of the keyboard connnectors to one
- of the gameport pins (I ran it to the leg of an adjacent chip per the
- instructions provided in a Videx 80-column card manual) *AND* added
- a tiny DPDT slide switch to the Keyboard Encoder Board after cutting the
- "butterflies" so you can either set the keyboard output (whether you can display
- it or not) to either uppercase-only or uppercase/lowercase shiftable. Running
- a little cable to a case mounted pushbutton switch would give you an actual
- Caps Lock key!

- Only on the ][ and earliest ][+ machines do you need a special chip for the
- character ROM. On a Rav.7 or later with the encoder board slung under
- the keyboard a standard 2716 with the appropriate characterset does fine.
